Hi Maria, thanks for reading! The 'Earths Currently needed' statistic is about the number of Earths we would need to sustain our current use of natural resources, including carbon-based energy sources. It's based on research by a climate organisation called Global Footprint Network; back in the 1990s they developed and helped popularise the concept of a 'carbon footprint'.
The year progress bar is more straightforward: it's simply about how far through the year we are. For example, at the time of writing it is the 56th day of 2022, which means we are approximately 15% of the way through the year.
Hello, David.
I wonder on the Humans of Earth section whats does it mean:
- Earths currently needed: needed of what? And what that number represents?
- 2022 progress bar: progress of what?
Thanks again!
Maria
